GRAIN SEPARA-fron.v
Application filed July 17, 1925. Serial No. 44,204.
To (all 'u1/loan t may concern.'
Be it known that l, Tirroims C. Hure-HIN- sorr, a citizen ot the United States, residing),` Duluth, in the county oit St. Louis and State ot illinuesota, have invented. certain new and useful lmproven'ients in Grain Sei arators, ot which the following' is a specilication, reference being had therein to the accompanying' drawing'.
This invention relates to `Lcanin separators and has special reference to an improved arrangement ot sieves tor such, the principal object being to incry ase the eiiiciency of separators as now used by the introduction of an additional sieve. Y
Other objects and advantages ot the peculiar construction and arrangement of parts Will appear in the Jfurther description of the invention.
Referring now to the accompanying draving, Lt'orming part of this application and in which like reference characters indicate like parts:
Figure 1 is a vertical diagrammatic view ot a `jrain cleaner or separator as'common in the art, it having` applied thereto my improved auxiliary sieve;
Figure 2 is a partial section on the line 2-2 Figure 1; and
Figure 3 is a partial section on the line 3 3, Figure 1. i Y
lIn Figure 1 is illust 'ated the common arrangement oi' major sieves in a reciprocating; or vibratingl separator, 1 representing the scalping sieve upon which, 'for example, wheat and oats are separated ,trom the straw and other foreign substance as they together are discharged downwardly through the feeding' spout Q onto said sieve, the Wheat and oats commonly falling through the sieve 1, while the larger material passes on downwardly on said sieve over the lowermost edge thereof'.
Spaced beneath the sieve l is the blank 3, it being in parallel relation to the sieve 1 and receiving the Wheat and oats as they tall 'from the latter', conveying them downwardly and over the innermost end o' said blank 3 Where they drop onto the long` Wheat sieve 4, which is inclined in the opposite direction and through which t-he Wheat is separated trom the oats, the former falling; therethrough onto the `tine seed sieve 5, all oit said sieves being oit the 'forai'ninons sheet metal type, and the arrangement as before stated common in the art.
Now, my improvement resides in installing, intermediate oif the scalping sieve 1 and the blank 3, and about equally distant therebetween, an auxiliary Wheat sieve (i, which is also parallel with the scalping sieve and the blank, and terminate directly above the ternfiination ot the latter. Mounted within theI space intermediate ot the discharge ends of the auxiliary Wheat sieve and the blank are a plurality of parallel inclined covered bridges or passageways 7 for the Wheat which is separated from the oats on the auxiliary Wheat sieve 6, so that the Wheat thus separated may pass over the gap between the terminus oiz the blank 3 and the front 8 ot the separator. The passages 7 are in Width about one-third less than the open spaces 9 therebetween and are covered with peaked roofs 10 so that the material not separated upon thel auxiliary sieve 6 will pass over the lowermost edge thereof andl tall intermediate oi' the bridges onto' the Wheat sieve l in much the ordinary manner, the bridges forming no obstacle to such passage, and the receiving end of the bridges provided With flaring guiding` Walls 1l so as to direct as nearly `as possible all the Wheat separated through this initial tall across the bridges 7, and from thence falling directly downwardly Y into the crescent shaped apron 12 externally of the front ot' the machine which directs it onto the tine seed sieve.
In this'manner it has been demonstrated thatapproximately 25% of the Wheat. may be separated from the oats on the auxiliary sieve 6 and pass, as before described, direct-- ly onto the seed sieve, providing; that much greater capacity ttor the wheat. sieve, and the capacity of the mill or separator is thus proportionately increased.
It is obvious that such addition to each separator is con'iparatively inexpensive.`
Having thus described my invention., what I claim and desire torsecure by Letters Patent, is:
1. The combination with a separator ot the type described including a scalping sieve and successively therebeneath, a blank, a Wheat sieve, and a tine seed sieve, of an auxiliary sieve intermediate of the scalpinf; sieve and the blank ter performing an initial wheat sieve, and a. [inc seed sieve, of an auxiliary sieve intermediate of thc scalping. 10
sieve and the blank for performing an initial separat-ion of the wheat from the oats.
In testimony whereof I-lieieunto aix my signature.
THOMAS C. HUTCHINSON.
